I'm about to have my 18 year old roofing shakes torn off and replaced with
Gerard stone coated steel roofing panels. Has anyone any advice regarding
this work on a 5:12 hip roof. I think they'll use Layfast underlayment and
add 1 1/2" foil faced fiberglass insulation between the battens. Any ideas
or opinions would be welcome.
Looks like an interesting roofing material. Should be great if
Your contract should include a specification for the underlayment
system. Layfast is a good product (about a 70 lb inorganic fiberglass
inorganic sheet - much better than felt). The insulation is required as
part of the installation spec. Considering that this roof could last
for 50 years, I'd be inclined to put down two plys of Layfast. Use
non-ferrous metal in the valleys (copper, or even galvalume) and insure
the valley metal is completely covered by the underlayment.
You might want to look over the ICC and Miami-Dade Product Approval
specs for this product just to see if there is information in there that
is of use to you.
take a look at decra.com by tasman. we had the shingles put down over
gaf metal-mate. they put the metal-mate over the entire roof before the
shingles. it is the same as ice guard i think except it has a metal top.
